Cellulosic biofuels, produced from nonfood feedstock, are expected to play a critical role in reducing the country's dependence on imported oil. EISA, the Energy Independence and Security Act of 2007, calls for the production of 100 million gallons per year (mgpy) of cellulosic biofuels by 2010, with a longer term goal of 16 billion gallons by 2022.Achieving these goals will not be easy. Several ...

In this study, the ability of various sludges to digest a diverse range of cellulose and cellulose-derived substrates was assessed at different temperatures to elucidate the factors affecting hydrolysis. For this purpose, the biogas production was monitored and the specific biogas activity (SBA) of the sludges was employed to compare the performance of three anaerobic sludges on the degradation ...

This article focuses on Cellulosic Pretreatment heating strategies with Direct Steam Injection (DSI) heating and how to transition from a lab environment to a successful process level production design. Typical applications include cellulosic & biomass ethanol processing, pulp stock processes, and other process fluid heating applications where fibrous materials are present in the process. ...

Biomass pellets energy means the energy made from biomass. What is biomass? Biomass refers to all the organic matters that store energy from photosynthesis. Therefore biomass in most cases means plants instead of animal. What is the chemical composition of biomass? Biomass is carbon based, so it contains ...

On January 13, 2017, the DOE Bioenergy Technologies Office (BETO), together with the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA), announced the intent to issue a request for applications (RFA) titled “Fiscal Year 17 Biomass Research and ...

The U.S. Environmental Protection Agency (EPA) has proposed the volume requirements and associated percentage standards that would apply under the RFS program in calendar years 2014, 2015, and 2016 for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel. We will include a complete analysis of the EPA ...

EPA announced that renewable fuels produced from sorghum biomass could qualify as cellulosic fuel under the Renewable Fuel Standard (RFS). This is a result of a preliminary analysis of the Greenhouse Gas (GHG) emissions resulting from the growth and transport of biomass sorghum feedstocks that are used to make biofuels. The analysis, which was conducted in response to a petition from the National ...

On December 14, 2015, the U.S. Environmental Protection Agency (EPA) published the Renewable Fuel Standard (RFS) Program: Standards for 2014, 2015, and 2016 and Biomass-Based Diesel Volume for 2017 in the Federal Register. The final rule will become effective on February 12, 2016, and establishes annual percentage ...

On December 12, 2016, the U.S. Environmental Protection Agency (EPA) published a final rule, Renewable Fuel Standard Program: Standards for 2017 and Biomass-Based Diesel Volume for 2018, in the Federal Register. This final rule sets the annual percentage standards for cellulosic biofuel, biomass-based ...

Promising advances using yeast and fungi. Written by Nancy W. Stauffer. You can read the original story in MIT News MIT researchers are genetically engineering yeast to break down stubborn plant fibers into sugars that it can then ferment — a first ...

On March 3, 2016, the U.S. Department of Energy (DOE) Bioenergy Research Centers (BRC) announced the 500th invention disclosure since 2007. The BRCs, which consist of the BioEnergy Science Center (Oak Ridge National Laboratory), the Great Lakes Bioenergy Research Center ...

Caldicellulosiruptor saccharolyticus is an extremely thermophilic, gram-positive anaerobe which ferments cellulose-, hemicellulose- and pectin-containing biomass to acetate, CO2, and hydrogen. Its broad substrate range, high hydrogen-producing capacity, and ability to coutilize glucose and xylose make this bacterium an attractive candidate for microbial bioenergy production. Here, the complete ...

Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. ...

Abstract Lignocellulose represents a potential supply of sustainable feedstock for the production of biofuels and chemicals. There is, however, an important cost and efficiency challenge associated with the conversion of such lignocellulosics. Because its structure is complex and not prone to undergo chemical reactions very easily, chemical and mechanical pretreatments are usually necessary ...

On June 24, 2015, the Master Limited Partnership Parity Act (S. 1656) was reintroduced in the House and the Senate. The legislation would provide investors in renewable energy projects with tax breaks that are currently available to investors in fossil fuel-based energy projects. A master limited partnership is taxed as a partnership, but ownership ...

On April 15, 2016, the U.S. Environmental Protection Agency (EPA) sent its newly proposed Renewable Fuel Standard (RFS) volumes for 2017 and 2018 to the U.S. Office of Management and Budget (OMB) for review. Under the Clean Air Act (CAA), EPA must set standards for cellulosic biofuel, biomass-based ...

Developments in the world of biobased products and bioenergy have flourished in recent years, as reported by sources such as The Carbohydrate Economy newsletter, the USDA’s Agricultural Research Service, the New Uses Council, and In Business magazine, among others. But while each new use for crop residues or another cellulosic ethanol project brings encouragement to sustainability proponents, the ...

As we all know that all natural resources on this earth are exhaustible sooner than later. At the current rate in growth of Energy Demand of the world, Fossil Fuels would last in the following order: Oil is expected to last only 45 years, Gas 70 years and Coal 250 years from now. The good quality coal of low ash content, however, may last only for another 70 to 100 years. Once these ...
